Description

Guide rail system and construction method for bridges {CONSTRUCTION METHOD AND DEVICE OF GUIDE-RAIL FOR BRIDGE}

The present invention relates to a guide rail device and a construction method of a bridge to be installed on the bridge to prevent the fall of vehicles and pedestrians and to mitigate the impact against accidental accidents.

In general, bridges have been installed to prepare for accidents, but they have simply fixed the guide rails to the concrete floor structure, and no matter how firmly they are fixed, they cannot absorb the impact force when they collide with the vehicle. There was a problem that the guide rail was broken and even the vehicle fell down the bridge because it could not absorb the impact force, and the vehicle was greatly damaged by the minor collision and the damage of the occupant was also continued.

In particular, since the guide rail of the bridge is installed at a considerable height from the ground, a more functional device is required for a traffic vehicle like a lifeline.

In order to solve the above problem, the present applicant has proposed a guide rail device and a construction method of a bridge with the registration number 10-393467.

However, when the guide rail device and construction method of the bridge are actually installed, the rib beam should be welded to the box-shaped post and the H beam should be fixed in three stages. However, the difficulty of fixing the fixing bolt inside the post has been generated. Even if they did, defects often occurred.

The present invention can easily install the H-beam attached to the guide rail of the bridge to solve the above problems, the guide rail device and construction of the bridge that can easily maintain the guide rail, thereby reducing the construction and maintenance costs It is an object to provide a method.

In order to achieve the above object, the present invention is a bridge guide rail device consisting of a rib plate that is fastened to the base plate on the concrete material with an anchor bolt and can be fitted into the H beam, the rib plate is A rib seating groove formed to attach the upper and lower rib plates to the front surface of the post; A lower rib plate including a reinforcing plate and welded to the rib seating groove and fixing the cushioning material and the H beam with a fixing bolt; Provided with the guide rail device and the construction method of the bridge that is coupled to the reinforcing plate is coupled to the upper rib plate that is fixed to the buffer material and the H beam with a fixed bolt.

Hereinafter, the configuration and operation of the present invention for achieving this purpose will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a guide rail device according to the present invention, Figure 2 is an exploded view of the guide rail device according to the invention, Figure 3 is a cross-sectional view of the guide rail device according to the invention, Figure 4 according to the present invention It demonstrates similarly as sectional drawing of an upper and lower rib plate.

First, the base plate 2 is installed using the anchor bolt 9 embedded in the poured concrete material 11, and then the post 1 is fixed.

Before fixing the post 1, the rib seating grooves 7 are formed by machining the rib seating grooves 7 having a proper spacing in three stages on the front surface of the post 1 so that the rib plates 6 can be seated.

In addition, the lower rib plate 6-2 having the tab holes 9 is formed to weld and attach the reinforcing plate 6-3 and fix the shock absorbing material 5 and the H beam 3 with the fixing bolt 8. Weld and attach to the bottom of the rib seating groove (7).

In the space formed inside the lower rib plate 6-2 coupled as described above, a rubber buffer material 5 and an H beam 3 are installed for shock absorption and shock relaxation.

Similarly, the upper rib plate 6-1 having the tab hole 9 formed thereon for fixing the buffer material 5 and the H beam 3 with the fixing bolt 8 is easily formed by detachment and attachment. ) And the H beam (3) is wrapped in the space formed therein to be seated on the reinforcing plate (6-3).

As described above, the buffer material 5 and the H beam 3 provided in the upper and lower rib plates 6-1 and 6-2 have tab holes 9 formed in the upper and lower rib plates 6-1 and 6-2. Fix it with fixing bolts (8).

At this time, the post 1, the attachment attached thereto, and the H beam 3, as in the prior art, may not only clean the aesthetics but also prevent rust, by coating the front part of the H beam 3. The impact protection cap (4) is used to alleviate the impact.

The impact protection cap (4) can be made of a FRP system or a hard rubber material and can not only look beautiful by diversifying the color, but also can be easily identified at night by luminous paint to prevent accidents in advance. The effect can be obtained.

The guide rail device of the bridge configured as described above is easy to construct and maintain, and the aesthetics are not limited to only the bridge, but can be used on general roads or high prices.

Next, the guide rail construction method of the bridge will be described. First, the base plate (2) welded to the post (1) after inserting the anchor bolt (9) in order to facilitate the installation of the post (1) in a predetermined portion of the bridge. ) To fix the post (1) using a nut.

Then, the rib seating groove 7 in which the proper spacing is maintained in three stages is formed on the entire surface of the post 1 so that the rib plate 6 can be seated.

In addition, the lower rib plate 6-2, to which the reinforcing plate 6-3 is welded and attached, is welded and attached to the lower portion of the rib seating groove 7.

The shock absorbing material 5 and the H beam 3 are installed in the space formed inside the lower rib plate 6-2 coupled as described above.

Similarly, after the cushioning material 5 and the H beam 3 are wrapped with the upper rib plate 6-1, which is easily detached and attached, it is allowed to be seated on the reinforcing plate 6-3.

The buffer material 5 and the H beam 3 are fixed with the fixing bolt 8 by using the tab holes 9 formed in the upper and lower rib plates 6-1 and 6-2.

After completing the construction of the guide rail of the bridge as described above, the impact protection cap (4) may be diversified to make the aesthetics look good, and luminous paint makes it easy to identify at night.

As described above, the inventors of the guide rail device and construction method of the bridge can easily install the H-beam attached to the guide rail of the bridge, easy maintenance of the guide rail, thereby reducing the construction and maintenance costs That's a useful way.
